Anaesthesia Monitor BIO-3A (Currently not available)

  • Pulse oximeter with ECG unit BIOSCOPE-D

This device stands out by the combination of a pulse oximeter and a separate usable (removable from the monitor) BIOSCOPE-D. Pulse oximeter and BIOSCOPE-D are united to a small compact monitor. The monitor could be used as a desktop model or fastened at an infusion stand by a tripod mount.

The anaesthesia monitor BIO-3A is suitable both for mains and battery operation. It also has built-in rechargeable batteries besides an external power supply. The operation time with fully loaded batteries is about eight hours. The batteries will be loaded with the monitors built-in charger. On the one hand the BIO-3A could be used in an uninterrupted mains operation mode at a permanent location, on the other hand a mobile use is also possible.

The monitor BIO-3 is not developed for bed-sided use. It is suitable for operations while medical specialist staff is in the proximity and can directly react to a triggered alarm.

Application range:

  • alarm function for SpO2 and heart rate
  • acoustic and optical signal for heart rate
  • due to built-in rechargeable batteries independent of the mains, therefore also suitable for transportable use
  • no small single devices with unsafe location
  • nevertheless ECG monitor BIOSCOPE-D also separate usable
  • data storage on PC

Standard accessories: ECG patient cable, oximeter finger sensor for adults, power supply
Optional accessories: tripod mount, PC software for documentation and evaluation: signal view of ECG and plethysmogramm, trend HR and SpO2, save, print, data export

Optional PC software for BIO-3A

The optional available PC software BIO-3A is the perfect tool to document the data derived from the anaesthesia monitor BIO-3A. So you can see the signals of ECG and plethysmogramm on a larger screen of a PC and watch the trend of heart rate and SpO2 in real time. Certainly it is possible to store the transmitted data for a later processing. The software has a built-in printing function for your documentation. Also is a data export possible.

Minimum requirements for the used PC:

  • Operating sytem: Windows 2000 or Windows XP
  • Memory: 64 MByte RAM
  • Available space on hard disk: 10 MByte plus size for storing measured values
  • Drive: CD drive
  • Screen resolution: at least 1024 x 768 pixel
  • Interface: serial interface (RS232)
